Answer: travel to other countries
Step-by-step explanation:
The independent variable is the one which brings changes in the another variable or dependent variable. The dependent variable is variable which changes due to manipulative changes on the independent variable.
The independent variable is the travel to other countries which is going exert it's influence over the increase in the ability to do well in advanced sociological classes.

Answer: The initial volume is 593.76mL
Step-by-step explanation:
As you do not say anithing about the pressure, i guess that the pressure remains constant.
If the gas is an ideal gas, we have:
P*V = n*R*T
where P is pressure, n is number of moles and R is a constant.
Now, initially we have:
P*Vi = n*R*315°C
finally we have:
P*825mL = n*R*452°C
Now we can take the quiotient of those two equations and get:
(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)
Now we have:
Vi/852mL = 315/452 
Vi =  (315/452)*852mL = 593.76mL
So when we expand the gas at constant pressure, we increase the temperature.
